The Equal Arm Balance was specially designed to simplify the study of torques. To put the balance in equilibrium, the clockwise torques caused by the weights to the right of the rotational axis must equal the counterclockwise torques caused by the weights to the left of the rotational axis. This balance has a ball-bearing pivot, and weights can be hung from the lower loops or from strings in the upper notches. Torques can also be exerted using spring scales.
